I was just wondering because I read this from wikipedia:
"He is celebrated in many churches on his feast days: 17 January in the Roman Catholic Church and the Eastern Orthodox Church; and (January 30) in the Coptic Orthodox Church, the Coptic Catholic Church and the Russian Orthodox Church"http://en.wikipedia.org/wiki/St._Anthony_the_Great
Now I know wikipedia isn't the best place to get info so that's why I wanted to post the question on here. My church also celebrates St. Anthony on Jan 30th, but on our church calendar it is Jan 17th as we follow the Julian calendar. So I was just a little confused on what the article meant but I guess it is just an old vs new calendar thing.
